To easily form various fountain shapes such as the shape of a flower by providing the end part of a conduit with a water-inducting plate extended on the side in the edge part of a fountain port and also providing the upper part of the fountain port with a baffle plate with the prescribed interval from the surface of the water-introducing plate and erecting a water current-changing plate in the peripheral part of the water-inducting plate.

When a pressurized water current flows upward through a conduct 4 and reaches the upper end of the conduit 4, firstly the pressurized water current collides against the rear surface of a baffleplate 10 and the direction of the water current is changed on the side and the water current is spouted from the center toward the whole direction of the periphery of the upper surface of a water-inducting plate 8. Then, the spouted water current collides against the lower end part of a water current-changing plate 16 and rises along the wall surface of the water current-changing plate 16 and spouts from the top edge part of the water current-changing plate 16 into the air and becomes so-called fountain. At this time, the shape of fountain is formed in accordance with the shape of the water current-changing plate 16. For example, in the case of forming the shape of the water current- changing plate 16 into an annular shape which is nearly tilted outward, fountain represents a flower like a lily of the valley because fountain falls down outward when the force of the water current is lost.
